Why the Zenith x USM DEFY Chronograph Has Become One of My Favorite Modern Watches

​Every so often, a watch lodges itself in my brain and simply refuses to leave. Not because it’s loud, rare-for-the-sake-of-rare, or chasing whatever the internet is obsessed with this week—but because it gets the fundamentals exactly right. The Zenith x USM DEFY Chronograph is one of those watches for me. Even months after its release, I still find myself circling back to it, mentally placing it alongside objects I genuinely love: furniture, architecture, lighting, and industrial design.

​What draws me in is how unapologetically design-driven it feels. The DEFY’s angular 37mm case has always had a slightly architectural quality, but here it feels fully realized—like a modular system rather than a standalone object. The geometry is crisp, intentional, and beautifully proportioned, echoing the logic behind USM’s iconic modular furniture rather than merely referencing it. This is a collaboration that understands why USM matters, not just how it looks.

​And then there’s the color. USM Green, Gentian Blue, Golden Yellow, Pure Orange—these aren’t necessarily “watch colors,” they’re more design-world colors. The kind you associate with studios, creative offices, and modernist interiors. I love that Zenith leaned into that identity fully, right down to the chronograph seconds hand tipped with a tiny USM ball joint. It’s fun, yes—but also deeply considered.

​Powered by the El Primero 400 chronograph movement, the watch grounds all this design talk in serious horology. It’s functional, historically significant, and beautifully executed. But more than anything, this is a watch that feels aligned with how we live with well-designed objects. The items I choose, the spaces I admire, and the idea that great design should feel just as good five years from now as it does today.
